Zhang Yang was very reluctant to let Yang Ling'er follow him to the mountain for an adventure, especially this experience of nine deaths and a lifetime, and now he still has palpitations when he thinks about it.

After thinking about it for a while, he had a bottom in his heart, so he said Ling'er, you can go up the mountain, but you have to promise me one condition.

"What conditions?" Yang Ling'er was full of joy. Women are timid, but she has a natural adventurous spirit.

"It's very simple, it's not allowed to run around after going up the mountain, and everything is up to me. ”

"When did I stop listening to you!" Yang Ling pouted, her face full of displeasure.

"Good, good. Zhang Yang thought to himself, women are really inexplicable, for no reason, why are they emotional?

He chuckled, "It's not okay if I'm wrong." Tell me about your good idea. ”

"That's pretty much it. Yang Ling giggled, "This is called 'Brother is on the wall, and the outside is insulted'." ”

Her words are from "The Book of Songs, Xiaoya, Chang Di". It means that although the brothers quarrel at home, they can unanimously resist the bullying of outsiders. Although there are internal divisions and disputes, they can unite to deal with external aggression.

Used here, it is natural to joke with Zhang Yang.

Zhang Yang smiled and didn't say anything, which means that you have something to say quickly, and if you have a fart, let it go.

Yang Ling'er seemed to know the meaning behind his smile. Big eyes blinked, and then said, "My method is to soak the main line through four mixtures such as HF + butter + baking soda, which can improve the toughness and transmission speed of the line." ”

Zhang Yang said, "Hf is the symbol of 'hafnium', a metal element, which seems to have no effect on the toughness and transmission speed of the line?"

"Add baking soda and other four mixtures!" Yang Ling'er emphasized her choice of words, adding: "The reason why my 'frog' work can track the details of the survival of real frogs is because of this technology. She looked excited.

"Wow, you've designed and made a work that can observe the living conditions of real frogs! Amazing! This work will definitely win an innovation award." ”

Zhang Yang clapped his hands and grabbed Yang Ling's hands, "Yes, such a simple method, Teacher Mao often mentioned it in class, why didn't I think of it?

"It's a fan of the authorities. Yang Ling'er broke free slightly, withdrew her hand, and her cheeks flushed. Slightly shy, his voice was obviously lowered, "Why are you bullying people!"

Zhang Yang let go of his hand but took the opportunity to kiss Yang Ling's cheek, which made her face even redder, "You're so bad!"

Zhang Yang smiled wryly, word by word, close to her ear, "In... Learn... School... Can... No... Dare... This... Village... Be... I... Family... Place... ......"

"So, so what...... You, what are you doing!" staring at a pair of big eyes, Yang Ling'er fully put on an awe-inspiring and inviolable look.

"I'll eat you! and listen to me for everything, I can't accept such a small action, it really is!"

"Say!" Yang Ling'er looked gloomy.

"I'm really angry! Come, come, look at my work. Zhang Yang smiled even more. changed the topic and pulled Yang Ling'er to the roof balcony.

"Hey! It's a big toy airplane! I thought there was something remarkable!" Yang Ling'er screamed and laughed, deliberately shouting the words "large toy airplane" very loudly.

After two hiatious sounds, Zhang Yang corrected and said, "This is my No. 001 reconnaissance plane." What a toy work that is contempt for my abilities and personality. ”

Yang Ling'er shook her hair. smiled. Didn't speak.

Zhang Yang opened the cover of the No. 001 reconnaissance plane, took out a few main main copper wires, and went down to the balcony. "Hafnium" is ready-made, stirred with butter, coated with baking soda, etc., on top of the copper wire, and placed on an iron basin. waved his hand and asked Yang Ling to help bring four bricks, set up an iron basin, and then made a temporary gasoline lamp and placed it under the iron basin to light it...... About half an hour or so, under the action of high temperature, the iron basin sounded a sizzling sound, and a puff of yellow smoke came out......

"Alright, alright, extinguish the gasoline lamp!" Yang Ling'er waved her hands and jumped her feet and shouted, like a flower butterfly with fluttering wings.

Peel off the "hafnium" that has changed its color and take out the copper wire. The color of the copper wire has not changed, but the brightness has increased by seven points.

Zhang Yang smiled and said wittily, "I've made a fortune and practiced gold bars!" went up to the roof balcony and connected the copper wire to its place.

After finishing, he snapped his fingers in satisfaction, turned around and asked Yang Ling'er, "You say, what is the effect of this?"

Yang Ling'er pretended to be unfathomable at the moment. Shook his hair. smiled. Didn't speak.

The two returned to the room, and Zhang Yang sat on the sofa to operate the keyboard.

With the change of the key code, the No. 001 reconnaissance plane flew to the back mountain and stopped over the main peak. On the screen: Perspective obstacle depth of 50 meters. Then he jumped out of a large house.

The two of them exclaimed in unison, "House!"

Yang Ling'er suddenly approached Zhang Yang's side, her voice trembling, "How can there be a house in the mountain......?"

Zhang Yang's attention was focused on the screen, and at this moment he was attracted by another shot, "Look, what are these things!

"Ahh But, but how come they don't have heads? Can you analyze what it is?" she almost pressed her face to Zhang Yang's face.

"Oh, I almost forgot about it. Zhang Yang tapped on the keyboard, and the monster on the screen quickly zoomed in: yellow and black hair all over his body, and his hands and feet danced rhythmically, just like a gorilla in a zoo.

To their horror, the thing had no head.

At this point, a line of small print appears in the lower left corner of the screen: This object is not an animal, it is not a machine, it is a combination of rubber and wood, its movement is controlled by an ultrasonic wave called GFT, and its function is to guard: it has the function of being invulnerable and powerful.

"What kind of monster is this!" exclaimed the two men, glancing at each other, as if looking for an answer from each other's mouths.

"How do these things get in when they are 50 meters deep from the skin of the mountain wall? Are there any holes to enter? Who created these monsters? Are they the 'ghosts' who are causing trouble in your village?"

Yang Ling'er asked four questions in one breath, staring at Zhang Yang with both eyes, hoping to get a satisfactory answer.

Zhang Yang was silent for a moment, and he also felt that there was no way to start this matter, but he thought that if he could catch these monsters, he still had a few problems that he hadn't cleaned up, and he would definitely be able to solve them.

Yang Ling'er touched his head and joked about whether he had a fever and talked nonsense. At this time, Zhang Yang snorted nervously and said that he knew the entrance.

"Where?"

"In one of the eight caves. ”

Without waiting for Yang Ling'er to continue to ask something, Zhang Yangyang waved his hand, "Look at it." "With the change of the key code, the No. 001 reconnaissance plane circled the eight caves of the main peak. After reading the search result prompt, I thought that these eight gullies are nothing more than in the order of ABC to H on the surface, nothing special, but the result prompt emphasizes a "eight" character. "By the way, that's how it should be!"

"What did you find?" Yang Ling'er couldn't wait.

Zhang Yang smiled and asked, "Ling'er, your arithmetic is okay, right?"

"What's wrong?"

"How much does it mean to go from 1 all the way up to 8?"

"36!" Yang Ling'er blurted out without thinking. Wonderingly, he asked, "What are you doing here?"

"Then count the monsters in the cave cave are also 36!"

"That's right, it's strange, one is not more, one is not less. How do you know?"

"I'm also estimating. That's right. I remember that Mr. Mao talked about 'modern gossip' in a class: it fully illustrates the role of science in contemporary times, and it seems so unfathomable, like gossip, which is incredible. Therefore, I think that the composition of these eight caves is also calculated according to the life and death gate of Bagua, but it is different from Bagua, so it is called 'modern Bagua'. We might as well calculate according to 'life and death', from A to H, and then to 'death and life', from A to H, and so on, until 36 integers, then, do you think that cave is the entrance?"

"It's hole D. Yang Ling'er blurted out, "But hole D is a dead hole!"

"To live is to die, and to die is to live. Bagua, Bagua, it is like the profound Zen principle of Buddhism, which is worthy of our laity to understand. Zhang Yang put his hands behind his back, shook his head, and looked like an old pedant.

"Alright, alright, don't stink of you. Teacher Mao is not like you. ”

Zhang Yang laughed loudly, "Let's take a look at my other works first." But let me explain in advance that I don't say good things, but rather point to shortcomings and make more suggestions. ”

……

It was noon, and Yangmei walked through the door with a basket full of dishes. Zhang Mingren is a big ghost, and asked his mother with an attitude of breaking the casserole and asking the end, "Mom, why are you so expensive today, will this beautiful sister be my future sister-in-law?" "Ask your brother about this to see if he has this blessing." Yang Mei said with a smile.

During lunch, Yangmei kept serving vegetables to Yang Ling'er. Zhang Ming's small eyes rolled, "Sister, let me ask you a question?"

"Well, what a question, you say. ”

"When did I call you sister-in-law?"

Yang Ling'er's face turned red. glanced at Zhang Yang, only to see Zhang Yang looking at him with a smile, he couldn't help but feel ashamed, and he couldn't wait to find a hole to get into.

Zhang Tieta laughed and said: "I'm still studying, of course it's not appropriate to talk about marriage." But my family Zhang Yang is really good. Yang Ling'er, after graduation, you choose a boyfriend, and it is right to find my Zhang Yang. ”

"You're thick-skinned, don't make fun of people. Yang Mei glared at her husband.

At this time, Yang Ling'er swept away the embarrassment just now and looked down-to-earth and generous, "Zhang Yang and I have always been good at school." After speaking, he glanced at Zhang Yang, who was stealing fun.

"That's right!" Zhang Tieta smiled even more.
